Abstract

Disclosed is a self-contained Solar Powered Proximity Security Device which operates both local devices, such as lamps, and remote devices through its internal encoder/transmitter. In its automatic mode the device may be operated and triggered by its own internal motion detector or from other local external devices connected to it, or by any combination of internal or external detection devices or switches. Response may be further conditioned by detected ambient or other conditions. For example, the light may not turn on during daylight hours or under conditions of low battery charge to conserve power for priority functions.

Claims

1. A solar powered proximity triggered light comprising:

means for collecting solar energy and converting it to electrical energy;

means for receiving and storing said electrical energy, output means including a light for utilizing said electrical energy operable in response to a motion detection means sensing motion, and means for conditioning the response of said output means in response to sensed ambient conditions.

2. A solar powered proximity triggered light according to claim 1 wherein:

said means for collecting solar energy and converting it to electrical energy comprises a solar cell.

3. A solar powered proximity triggered light according to claim 1 wherein:

said means for receiving and storing said electrical energy comprises a battery.

4. A solar powered proximity triggered light according to claim 1 wherein:

said output means for utilizing said electrical energy further includes a transmitter means for initiating further response in response to said motion detector means sensing motion.

5. A solar powered proximity triggered light according to claim 1 wherein:

said means for sensing motion comprises an infrared motion detection device.

6. A solar powered proximity triggered light according to claim 1 wherein:

said means for sensing ambient condition include a photocell for sensing the lack of ambient light as a condition for operating said output means to light a light.

7. A solar powered proximity triggered light according to claim 1 further comprising:

means for detecting the state of energy storage.

8. A solar powered proximity triggered light according to claim 7 wherein:

said means for detecting the state of energy stored detects low battery storage and in a priority sequence reduces or eliminates light output in favor of operation of said transmitter means as a signal device.
